As teammate Christian Atsu, Kelvin was sent on loan to fellow Primeira Liga side Rio Ave F.C. for the 2011–12 campaign. He made his debut in the competition on 21 August 2011, in a 0–1 away loss against Académica de Coimbra.
Kelvin returned to Porto for 2012–13, spending most of the season with the B-team in the second division. He managed to score, however, three important goals for the main squad as a substitute, helping to home wins against S.C. Braga (3–1) and S.L. Benfica (2–1), the latter coming in the 92nd minute.
